感谢您的查询和屏幕截图。
使用Aspose.Cells API，您可以在电子表格/工作簿中创建MS Excel图表（标准，高级和自定义）。请参阅关于如何在Excel文件中创建自定义图表的文档主题：
关于生成带有两个y轴的图表，您可以根据需要尝试使用Series.PlotOnSecondAxis布尔属性。我已经编写了一个关于如何创建一个带有两个y轴的自定义图表的示例代码，供您参考。请参考它，您可以根据您的要求编写自己的代码:
e.g
Sample code:
//Instantiating a Workbook object
Workbook workbook = new Workbook();
//Get the first worksheet in the workbook
Worksheet worksheet = workbook.Worksheets[0];
//Adding a sample value to "A1" cell
worksheet.Cells["A1"].PutValue(50);
//Adding a sample value to "A2" cell
worksheet.Cells["A2"].PutValue(100);
//Adding a sample value to "A3" cell
worksheet.Cells["A3"].PutValue(150);
//Adding a sample value to "A4" cell
worksheet.Cells["A4"].PutValue(200);
//Adding a sample value to "B1" cell
worksheet.Cells["B1"].PutValue(60);
//Adding a sample value to "B2" cell
worksheet.Cells["B2"].PutValue(32);
//Adding a sample value to "B3" cell
worksheet.Cells["B3"].PutValue(50);
//Adding a sample value to "B4" cell
worksheet.Cells["B4"].PutValue(40);
//Adding a chart to the worksheet
int chartIndex = worksheet.Charts.Add(ChartType.Column, 5, 2, 21, 15);
//Accessing the instance of the newly added chart
Chart chart = worksheet.Charts[chartIndex];
//Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B4"
chart.NSeries.Add("A1:B4", true);
//Setting the chart type of 2nd SeriesCollection to display as line chart
chart.NSeries[1].Type = ChartType.Line;
chart.NSeries[1].PlotOnSecondAxis = true;
chart.SecondValueAxis.IsVisible = true;
chart.PlotArea.Area.ForegroundColor = Color.White;
workbook.Save("e:\\test2\\out1.xlsx");
希望，这有帮助。
感谢您分享示例文档。请注意，目前Aspose.Words不支持创建组合图表。我们已经在我们的问题跟踪系统中登录了一张门票 WORDSNET-12769 来实现此功能。我们将您的帖子与问题ID相关联，并在实施后立即通知您。
谢谢回复。祝你工作顺利，万事如意
